Although not as popular as some of his other works, Abraham Lincoln’s speech at Peoria, IL—delivered over the course of some three hours on October 16, 1854—is one of his more important public addresses. The speech combines history, reason, and moral appeal in an attack on the extension of slavery. Lincoln was no abolitionist—he did not call for the immediate eradication of slavery in states where it had always existed—but he considered its extension north of the Missouri Compromise line to be both a moral and a political wrong. The compromise had held for more than thirty years before Stephen Douglas’s Kansas-Nebraska Act overturned it in 1854 by permitting slavery in northern territories whose populations voted to permit the institution.

The Peoria speech contains one of my favorite passages from the entire Lincoln corpus:

Before proceeding, let me say I think I have no prejudice against the Southern people. They are just what we would be in their situation. If slavery did not now exist amongst them, they would not introduce it. If it did now exist amongst us, we should not instantly give it up. This I believe of the masses north and south. Doubtless there are individuals, on both sides, who would not hold slaves under any circumstances; and others who would gladly introduce slavery anew, if it were out of existence. We know that some southern men do free their slaves, go north, and become tip-top abolitionists; while some northern ones go south, and become most cruel slave-masters.

It’s a surprisingly charitable statement for a speech devoted to a divisive political issue, especially since Lincoln believed the stakes in the debate over slavery in the territories to be incredibly high.

In fact, in the same speech he denounced slavery as a “monstrous injustice” and its spread as an existential threat to American principles which “forces so many really good men amongst ourselves into an open war with the very fundamental principles of civil liberty—criticising [sic] the Declaration of Independence, and insisting that there is no right principle of action but self-interest.” Since Lincoln saw the slave question in such stark and consequential terms, the natural thing to do would have been to demonize those who upheld the institution and its extension. He not only refrained from doing so, but asserted that only historical circumstances accounted for the difference of opinion.

Perhaps one of the reasons for his refusal to castigate the South over the slave issue was the fact that he believed it such a difficult problem to solve. Lincoln freely admitted that he couldn’t prescribe a remedy for slavery. He told the Peoria audience that his “first impulse would be to free all the slaves, and send them to Liberia,—to their own native land.” He dismissed the prospect of granting them social and political equality, stating that his “own feelings will not admit of this; and if mine would, we well know that those of the great mass of white people will not.” Lincoln did believe “that systems of gradual emancipation might be adopted; but for their tardiness in this, I will not undertake to judge our brethren of the south.”

To modern ears, Lincoln’s desire to see the freedmen sent out of the country and his unwillingness make them his equals make him seem woefully backward. But his conviction that the slave question had no easy answers was one of the reasons he was reluctant to condemn those who disagreed with him about it. Faced with the most divisive, emotive political issue of his time, Lincoln did not assume that individuals on the other side of it were his moral inferiors. Even as he demonized the institution of slavery, he humanized those who disagreed with him about it. This willingness to distinguish between issues and their proponents would serve him well when he presided over a nation at war, a war that gave him the opportunity to enact the sweeping solution to the slavery problem from which he shrank in 1854.

For anyone trying to evaluate Lincoln as a moral role model, the Peoria speech shows him at both his worst and best. His remarks about political and social equality between whites and blacks revealed him to be a man of his time with all the attendant prejudices. On the other hand, the empathy he expressed toward the South seems remarkably enlightened by any standard of political rhetoric. Most modern Americans have long since outpaced Lincoln in terms of our beliefs about race, but in terms of knowing how to handle emotive political issues it seems we haven’t caught up with him yet. He knew that you could attack people’s opinions without attacking the people themselves. That’s a lesson we could learn today, when political differences remain as heated as they were in Lincoln’s day.
